The idea

The story of Lambach Aircraft started at TU Delft’s Faculty of Aerospace Engineering during the spring of 1989. At the time many students were thinking about good ways to honor the upcoming lustrum of the student society VSV Leonardo Da Vinci. Among them was Hans Blaauw, who conceived the spectacular idea of the students building their own flying aircraft. Next to honoring the VSV’s lustrum, this project could also provide the students with valuable practical experience by putting the theory learned at the faculty into practice. The original idea was to replicate Anthony Fokker’s famous flight around Haarlem’s St. Bavo Church. Later it was decided to build a replica of the Lambach HL II instead. Major reason for the switch was that the Aviodrome had a large set of technical drawings available, which would facilitate the build. Additionally the link with the university (Hugo Lambach was a Delft graduate) was a nice given.

Diplome Phénix

Because the drawings in the Aviodrome were quite vulnerable, these had to be copied first. A first dedicated group of Lambach Aircraft volunteers finished the copies in the summer of 1989, which meant that by September the actual production of the replica could start. To oversee the construction, Lambach Aircraft was founded on January 19th 1990 under its original Dutch name “Stichting Studenten Vliegtuigontwikkeling, -bouw en –beheer” or SSVOBB. The initial plan to build the aircraft in 5 months, just like the original, proved too ambitious.  Even with the help of the original HL II’s chief-engineer, Wim de Koo, it would still take over five years to complete the build. Despite the delay, Lambach Aircraft persevered and in 1995 the aircraft made its first flight. Little later the society received in the FAI’s prestigious “Diplome Phénix” for this achievement.

The Impuls

Back in 1994, with the HL II project nearing completion, a group of volunteers started working on the Impuls. Goal of the project was to build an aircraft fully designed by the students and as such it was the next logical step forward for the society. The initial progress was very promising and even the first parts were build. Later periods however were characterized by setbacks and attempts to get the project back on track. Eventually in 2010 it was decided to freeze the project.


The Impuls however was a valuable learning experience for Lambach Aircraft and its volunteers. It was thus logical that later in 2010 the S-Vision project was set-up, building upon the lessons learnt from the Impuls. By 2013 a major milestone was reached with the completion of the aircraft’s preliminary design, meaning that the outer dimensions of the aircraft have been fixed. Currently work is steadily progressing on the detailed design, bringing closer the realization of the society’s dream of designing, building and maintaining its own fleet of flying aircraft.
